4L60E questions
4L60E questions Hey, i'm new to 4th gen f-body's, and just got a 1998 T/A with the 4l60E auto. A couple questions I have are: In parking lots, or at low speed, is it normal for it to hold first gear till like 2k rpm, then shift? Mine does this and the 1-2 shift feels kinda rough in parking lots and such. Also, when i'm giving it a full speed run from say 0-50 and I run it up to like 5k rpm, then back off, is it normal for it to hold the gear and keep the high rpm's for a couple seconds, cause mine does that too. Mine also makes a strange noise when I shift into R. Sounds kinda metallic, I'm gonna go get it looked at this week I think. Anyway, if anyone has the answers to any of these questions, i'd appreciate the help.
It isnt that No ones seeing , just that there are so many possibilites and you have allready said you were going to have it checked , Do you have a check engine light on or anything?

Nope. And it's possible that i'm just paranoid. It's my first v8 F-body. Perhaps the 4L60E just feels different as well. I'm kinda used to the 700R4 in my 91 RS. It seems to shift fine, but the noise when I shift into R concerns me, as well as the fact that the trans seems reluctant to shift when making a 0mph run with full throttle.
Yea I'd say your safe in the aspect of it staying at 5k for a couple then shifting..these transmissions shift hard as hell. But i would definitely get the reverse sound checked out.

Cool. Yeah, hard shifts don't bother me, but the reverse noise does, so that will be looked at. I think i'll get a flush&fill for good measure too. Also, why does the trans hit first so late when dowshifting. Lke, when i'm coming to a stop, I feel it hit the 2-1 shift at like 10mph. It's weird cause it's right before the car comes to a stop. Does it hold second that long for better mileage or something?

sometimes when im in the parking lot setting and theres slow stop and go driving I feel like its in 2nd while im going like 2mph or real close to a stop. if i go it goes and then like drops into 1st like a clunk. like it wasnt ready to go and i gave it too much throttle. but at wide open throttle from that there no problem.

My tranny does same thing. I know mine is in need of a tune, but it holds in 1st till about 1800 then shifts, also if I hit the gas hard and let off of it, it slowly comes down from 5000. Same problem with braking, I can feel it shift into 1st as im coming to a stop. My reverse is also making a noise but its not metallic sounding, sounds more like a dull vibrating, only when cold though....
I'm not sure the shift when braking is even a problem. I think GM just chose a really low shift point. I'm actually starting to get really used to it. I noticed that our cadillac does it too, it's just not as noticable cause it's a gentler trany/fwd car. I think the trans is fine. Just need to get that reverse noise checked. That'll happen in the next couple days, and i'll let ya'll know what they tell me.
